On the Support Genus of Legendrian Knots
Sinem Onaran
In this paper, we show that any topological knot or link in sits on a planar page of an open book decomposition whose monodromy is a product of positive Dehn twist…

Exceptional Legendrian torus knots
Hansjörg Geiges, Sinem Onaran
We present classification results for exceptional Legendrian realisations of torus knots. These are the first results of that kind for non-trivial topological knot types. Enumerati…

On overtwisted contact surgeries
Sinem Onaran
In this note, we obtain a new result concluding when contact (+1/n)-surgery is overtwisted. We give a counterexample to a conjecture by James Conway on overtwistedness of manifolds…
